recommend a type of hrv/erv for condo in a highrise
Comments (3)I think your confusing open-air ventilation as a function of ERV's and HRV's, and it is not a functional "economizer". The purpose of the ERV is Sensible and Latent, and a HRV is Sensible only. Sensible is temp, latent is humidity. HRV's/ERV's attempt to maintain the same or close to the climate indoors while exchanging air. Thus a 80% efficient HRV/ERV will only lose about 20% of the indoor conditioned air at the rated CFM. That means the air exchanged with outdoors is returned to the space at the efficiency rating, which would do little for cooling. 200 CFM HRV/ERV will bring in the 40 CFM of cooler/warmer air with the temp basically split between indoor and outdoor temps. A HRV/ERV will give you the fresh air, if you ever have a need for cooling, the AC unit will still be required....See MoreHigh-rise Dwellers: Did you encounter these ventilation issues?
Comments (12)I have only seen this on a previous project in NJ. The other buildings with this system would not even allow vent hoods to use the system due to fears of grease build up. I don't know that there is a "CFM" that you will experience, but the working system I saw did NOT perform particularly well. For a normal cook it was adequate at best, for someone doing high heat/smoke/grease cooking (wok, frying etc) it was not nearly effective enough....See MoreBathroom sinks have water coming up from drain in a highrise
Comments (18)A slow drain is first cousin to your next stopped up and overflow. It’s a partial clog and drain cleaner is useless. Drain chemicals are actually VERY DANGEROUS YO YOU. It will burn you. It will dissolve the heck out of marble tile Heck, it can eat the gloss right off of ceramic tile. It can eat holes in galvanized plumbing and make a bad situation much worse. It’s not really safe to use and should be taken off the market. That drain needs to be augured. You obviously aren’t up to the task. Pay a Pro. Or have the super do the job he gets paid to do. And you better darn well be sure that your insurance covers flooding from negligence. Because it probably won’t. And your neighbor is gonna have a 59K judgement against you for ruining his apartment. If you rent instead of own, you will be asked to leave. If you own, the super is going g to have the right to enter your apartment at will to inspect, because you were negligent in reporting issues that caused building damage. What kind of “home professional” are you? Dare we ask? CPA? Accountant? Masseuse? All three? It certainly doesn’t involve anything design or construction related, that’s for sure....See MoreHow 2 install Freestanding bathtub in highrise condo w/ concrete floor
Comments (15)I live in a condo with concrete floors. I was also on the "architectural committee" which approved proposed renovations. Any time there was a proposal that would entail moving plumbing lines, we would insist on having a third party plumber/engineer review the plans at the homeowner's expense to provide us with opinions as to whether it should be done. We would also have required a covenant running with the land the warranted the change in plumbing in the event of any kinds of issues. Because of the extreme potential issues for plumbing changes most well run condos are extremely leery about doing anything that alters the infrastructure. For instance what happens when a homeowner on the top floor does some kind of Mickey Mouse plumbing and every unit below is flooded such the people have to move out while their units are completely reconstructed. I recently finished a remodel in my condo and I got rid of the tub/shower combo for a larger shower. This required a change in the drain - although it was located in the same position as tub drains are different than shower drains. As posted above, besides approval from the Board I also had to get permission from my downstairs neighbor to break into his ceiling so my pipes could be accessed. This cost approximately $1000 just for the demo and repair to my neighbor's ceiling. Luckily I am friendly with him and his ceiling wasn't special - just plain drywall. Other people in my building have "fancy" ceilings and approval to demo them would have been more expensive and potentially difficult to get....See More- 8 years ago
